Stila Stay All Day lives up to its name completely. This liner stays put for 12+ hours without fading, smudging, or transferring. The ultra-fine tip is the perfect balance of firm and flexible, making precise application effortless. The pigmentation is intensely black with a single stroke. I can create the thinnest lines or thick dramatic wings with complete control. The formula dries quickly and sets to a waterproof finish that doesn't budge. It removes easily with oil cleanser without harsh rubbing. One pen lasts me 4-5 months with daily use. At $24, it's pricier than drugstore but the quality and longevity justify it. This is the only eyeliner that never lets me down. My wings are sharp and perfect every time. I've repurchased this countless times and will never switch.
